What would most likely be the result of a malfunctioning liver? difficulty passing urine inability to grow hair buildup of toxins limited feces production

The correct answer is accumulation or buildup of toxins.  

One of the vital activity of the liver is to process various kinds of toxins and eradicate it out of the organism's system. Though it is known as a toxin processor, it is not impervious to the toxins itself. As the liver is the main site for drug detoxification and activation, thus, the malfunctioning of the liver will result in the accumulation of toxins.  

this would be a math

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
